The Ratel-90 is a South African IFV. It was introduced in the mid 1970s. It had large doors on each side to allow passengers in. It is armed with a 90mm autocannon and two MG-4s. The first MG-4 is part of the turret-mounted 90mm autocannon and the second is mounted on the back and manned by a soldier. The windows support small firing ports, four on each side.
